run code in 300+ PHP versions simultaneously
<?php class A { protected $b; public function a() { return $this->b->b(); } } $impl = new A(); //$impl->a(); call_user_func(null);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
